System installation

APPLICATION

GRB100 can be applied for various busbar systems.

Single busbar Double busbar One and a half busbar Four buscoupler busbar Ring busbar Busbar with transfer bus

GRB100 has a Central Unit (CU) and Bay Unit (BU).

The CU performs the protection calculations, scheme logic processing, recording, relay setting and display. The BU is a terminal used to acquire analog data from each CT which is converted to digital data for transmission to the CU via optical cable. It also receives the trip command from the CU and performs tripping of the circuit breaker.

The CU can be provided with an optional voltage check element.

GRB100 can be applied using one BU with two channels catering for two bays or one BU per bay provided with one channel.

A system installation using one BU per bay is shown in Figure 1.

The CU and BUs are linked via fibre optic cable with connector, type GHEV4002.

GRB100 provides the following protection schemes.

Busbar protection Circuit breaker failure protection End-fault and blind-spot protection

The busbar protection utilises two current differential elements.

a) Discriminating zone element to discriminate the faulted busbar. (four zone elements provided)

b) Check zone element covers the whole of the substation to detect faults on any busbar section.

By using these two elements, the GRB100 ensures a very reliable protection for various types of busbar system.

Figure 2 shows a typical application to a double busbar system. DIFCH is the check zone element which covers all busbars. DIFZA and DIFZB are the discriminating zone elements for busbars A and B respectively.

The voltage elements UVSFA, UVSFB, UVGFA, UVGFB, OVGFA and OVGFB can be provided for each busbar as fault detection elements (optional).

In this application, a faulted busbar section is confirmed by operation of the check zone element, a discriminating zone element and an undervoltage element.

A CT or CT secondary circuit failure will not cause a false operation.

GRB100 provides the following metering and recording functions.

Metering Fault record Event record Disturbance record

GRB100 provides the following user interfaces for relay setting or viewing of stored data.

Relay front panel (CU): LEDs, LCD display and keypad

Local PC Remote PC

A local PC can be connected via the RS232C port on the front panel of the CU. A remote PC can also be connected through the RS485 or Fibre optic port at the rear of the CU.

RELAY FUNCTIONS

Discriminating Zone and Check Zone Elements The check zone element (DIFCH) and discriminating zone elements (DIFZA - DIFZD) are based on the current differential principle and has a differential characteristic for the small current region and a percentage restraint characteristic for the large current region as shown in Figure 3.

The percent slope of the restraint characteristic in the large current region is variable.

CT saturation under external fault conditions can be a serious problem for busbar protection. GRB100 overcomes the CT saturation problem by using a “CT saturation detection” function. When an external fault occurs, a very large erroneous current may be caused by CT saturation. However, once the CT saturates, there is a short period of several milliseconds of non-saturation between the saturation periods in a cycle. By detecting this non-saturation period, the current differential element can be blocked to prevent false operation arising from CT saturation.

Figure 4 shows the block diagram for the current differential element.

Figure 5 shows the scheme logic with check zone, discriminating zone and voltage check element for a double busbar system.

Breaker Failure Protection Phase-segregated breaker failure protection is provided for each bay and can be initiated by either an internal or external signal.

When an overcurrent element remains in operation after a tripping signal has been issued the breaker is judged to have failed and a 2 stage CBF sequence is initiated. The first stage issues a re-trip command to the circuit breaker. If this also fails then the command to backtrip adjacent circuit breakers is excuted. The overcurrent element has a high-speed reset time.

GRB100 has two kinds of timer for Breaker Failure Protection. One timer is used for re-trip, the other timer is used for CBF trip.

A remote transfer trip is provided for feeder circuits.

End-Fault and Blind-Spot Protection This function is provided to cater for circumstances when a dead zone or blind-spot is created between the CB and the associated CT.

End fault protection detects a fault located between the CB and the associated CT when the CB is open. Depending on the location of the CT, either the busbar section CB is tripped or an inter trip is sent to the CB at the remote end of the line.

Blind-spot protection is used to detect and trip for faults located between the bus-section CB and the associated CT for the arrangement when the CT is installed on one side of the CB only.

BU Out-of-Service Function GRB100 provides a BU out-of-service function for maintenance purposes.

Voltage Check Function (option) GRB100 can enhance security against false tripping due to a failure in a CT or CT secondary circuits by the provision of a voltage check element in the form of a check relay with circuits that are independent from other circuits:

The voltage check function incorporates the following elements.

Undervoltage element for earth fault detection Undervoltage element for phase fault detection Zero-phase overvoltage element for earth fault

detection Undervoltage change detection element for

circuit breaker failure protection

Current Transformer Requirements The GRB100 does not require the use of dedicated CTs nor the use of CTs with an identical ratio. The GRB100 can share CTs with other protections and different ratios can be adjusted by setting.

The general CT requirements are determined for through-fault stability which caters for the condition when CTs saturate for very large through-fault currents. To ensure correct operation of the GRB100 for such through-fault currents, the factor Ks for each CT is required to satisfy the following conditions:

Ks ≧ 1 when Tc ≦ 200ms or Ks ≧ 2 when Tc ≦ 250ms

where,

Ks = ratio of CT knee point voltage to CT secondary voltage predicted under the maximum through-fault current

= Vk / {(RCT + RL + RB + RO )(IFmax / CT ratio)} Tc = d.c. time constant of primary circuit Vk = knee point voltage of CT RCT = resistance of CT secondary winding RL = loop resistance of cable between CT and relay RB = ohmic load of GRB100 bay unit (i.e. 0.1 ohm for

1A rating and 0.012 ohm for 5A rating) RO = ohmic load of other series-connected relays (if

any) IFmax = maximum through-fault current

For example, if the following parameters are given:

Vk = 800 V, CT ratio = 1200/1, RCT = 5.0 ohm, RL

= 3.0 ohm, RB = 0.1 ohm, RO = 0 ohm (i.e. no series-connected relays) and

IFmax = 40kA

Then the factor Ks is calculated as:

Ks = 800/{(5.0 + 3.0 + 0.1)×(40000/1200) } = 800/270 = 3.0

This shows that the GRB100 will operate correctly for all faults under the condition that the d.c. time constant of the primary circuit is less than 250ms.
